Surface blend

Hi, I would like to join and blend these 4 surfaces in a smooth way, but I have tried command blend surface, match surface even patch command, I still cannot fix it. Any help please! The shape of surfaces at the end need to be remained, the surface at the middle can compromise a little bit. Please have a look at the rhino file, thanks!
